We had a 3 hours tour with Mirjana seeing the lower lakes, some parts of the upper lakes and having a boat tour. Mirjana lives in the area and is very knowlegeable about the lakes and the park. She is punctual, friendly and nice. Her english is very good. We had limited time to see the park and in 3 hours we had a very good tour of the main sights. Thank you Mirjana for the great excursion. Wish you the best!
